I think very slightly. Take a look at the display powered but at 0 brightess in a darkened room - you will see glowing red filaments. These are the cathode filaments, see: http://en.wikipedia.org/wiki/Vacuum_fluorescent_display http://hem.passagen.se/communication/vfd.html Those VFDs are kept red-hot as long as power is applied, even when the display is dark. They are -very slowly- degrading - emitting electrons on a continuous basis. While they're not boiling away like an ice cube, over the years it does add up. May take 20 years (who knows) but they don't last forever. Dimming the display away from full brightness also avoids burning in the phosphors. Burn-in on the displays used in the Squeezebox and the Transporter is very rare but there was a mention or two on the forums about this. So on idle screensaver mode you'd be wise to set your brightness less than full. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29777 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
